Well im having the same problem I think,lol if i read your post right. Same year same model. I am not sure how the spark should look,it looks kinda weak to me. I put a spark tester in the plug boot and the light glows orange(by the way its one of those harbour freight spark tester) so i assume it has good spark. I also tried the plug in the boot and then plug to ground , when I do it that way I get no spark except one time i actually put the plug dead on the exhaust pipe and i got a ok spark. I just replaced the stator with a new to me part...and its getting gas ,casue everytime i pull the plug it has fuel on it.....i sprayed ether in it still not even a pop or a back fire. i marked my old stator b4 i removed it , and replace the new to me stator in its exact spot.Do i need to adjust the stator for optimum spark capacity....Sorry for hogging your thread...PLEASE HELP US !!!!
